Definitions
- the present invention generally relates to a waste transfer system for a toilet of a public transport vehicle that discharges into an on-board waste storage tank.
- a waste transfer system for a toilet, or similar sanitary appliance that discharges into an on-board aerated waste storage tank that may subjected to biological waste treatment.
- EP0584031 discloses a waste transfer system including one of these type of waste storage tanks where a discharge valve is arranged between the toilet bowl and the said waste storage tank to open or close the passage of fluid through the waste storage tank.
- Document EP1013838A1 discloses a vacuum sewer system including a sanitary unit subjected in use to periodic emptying cycles, a first sewer pipe connected to the sanitary unit via a normally closed first sewer valve, means for generating vacuum in the first sewer pipe and means for subsequently operating the first sewer valve to allow a vacuum induced waste transport from the sanitary unit through the first sewer pipe.
- the vacuum transport of waste material from the sanitary unit is carried out in two stages, the first stage including, waste transport from the sanitary unit through said first sewer pipe to an intermediate container, and the second stage including waste transport under vacuum from the intermediate container through a second sewer valve and a second sewer pipe to collection means or sewage means when the connection between the sanitary unit and the first sewer pipe is closed.
- the two sewer valves are functionally interconnected and combined into a single valve device connected to the first sewer pipe and the second sewer pipe.
- the system used to transfer the waste from the bowl to the aerated waste storage tank forms part of each toilet bowl and includes a small intermediate waste tank next to each bowl.
- This intermediate waste tank is used to first generate a local vacuum to transfer the waste from the toilet bowl to the waste intermediate tank by the opening of a valve located between the toilet bowl and the said waste intermediate tank. Having accomplished this, this valve is closed, the intermediate tank is pressurized and a second valve located at the exit of the waste intermediate tank is opened allowing the waste to be transferred through an interconnecting tube to the aerated waste storage tank.
- waste transfer systems with aerated waste storage tanks although more complex and demanding than waste transfer systems with vacuum waste storage tanks, have the advantage that allow the use of biological waste treatments which extend the emptying periods of the waste storage tanks to weeks or even months. Nevertheless, these waste transfer systems have the drawback that they have a high requirement of room needed for the installation next to each toilet bowl.
- the present invention relates to a waste transfer system as claimed in claim 1 that discharges into an on-board waste aerated storage tank.
- the multi-port discharge valve connected to an inlet/outlet port of the waste intermediate tank allows to overcome the above-mentioned shortcoming of the prior art aerated waste transfer systems. Indeed, it has been found that the requirement of room is significantly reduced because this multi-port discharge valve may be installed next to each toilet bowl beside the waste intermediate tank, and the design of this waste intermediate tank may be improved to take advantage of extra free room available below the toilet bowl. On the other hand, a waste transfer system with a higher reliability is obtained because the claimed waste system facilitates the location of the blockages caused by foreign bodies in the toilet such as syringes, sanitary towels, tampons, disposable razors, among others
- the multi-port discharge valve is connected to a port which is a single inlet/outlet port of the waste intermediate tank and, more preferably, said multi-port discharge valve is a single 3-way discharge valve, or a discharge valve with three ports, connected to the inlet/outlet port of the intermediate waste tank.
- the discharge valve is connected to a first inlet port of the port of the waste intermediate tank and to a separated second outlet port of the port of the waste intermediate tank, and said discharge valve comprises 3-way valve with four ports adapted for opening or closing the first conduit as a waste passage of fluid in the first working position and for opening or closing the second conduit as a waste passage of fluid in the second working position.
- the above mentioned 3-way valve with four ports comprises a valve body and a rotating element adapted for opening or closing the passage of fluid between said toilet bowl and said intermediate waste tank in said first working position, and adapted for opening or closing the passage of fluid between said intermediate waste tank and said waste storage tank in said second working position.
- the valve discharge means further comprise driving means for said rotating element.
- said valve body is of synthetic material and, according to the present invention, said rotating element is housed in a cavity of said valve body.
- said rotating element is provided with a first conduit which, when the valve is in said first working position, connects the first port of the valve body to a second port of the valve body, and provided with a second conduit which, when the valve is in said second working position, connects the second port of the valve body to a third port of the valve body.
- the rotating element is adapted to avoid the communication between the toilet bowl and the waste storage tank when working in either said first or second positions.
- the rotating element is a tubular element provided with an interior separation plate adapted to avoid the direct communication between the toilet bowl and the waste storage tank in either said first or second working positions of the discharge valve.
- Said separation plate defines inside the said tubular element said first and second conduits of passage of fluid in said first and second working positions.
- said valve discharge means comprise a drive motor for said rotating element, and said rotating element comprises means for engaging a shaft of said drive motor.
- the shaft of said drive motor is arranged to directly engage an element, such as a gear wheel, provided in the outer surface of said rotating element. This arrangement helps obtaining a more compact solution.
- the discharge valve means comprise a plurality of positioning sensor readings attached to said rotating element.
- these sensor readings may be integrated in a plurality of notches provided in the body of the rotating element and may cooperate with sensors provided in the system and governed by a central controller unit.
- the claimed waste transfer system comprises a waste cutting element arranged between the adjacent surfaces of the second port of the valve housing and the rotating element. This cutting element may be configured by way of a steel-ring located at the outlet part of the valve body connecting to the intermediate tank and is so arranged that eventual solid parts upon valve closure are conveniently cut thus no preventing the valve from closing.
- the present invention relates to a waste transfer system for a toilet of a WC cabin of a public transport vehicle, for example a toilet of a railway vehicle that discharges into an on-board waste aerated storage tank.
- the system comprises a waste intermediate tank 1 for temporarily receiving the waste coming from a toilet bowl 2, a multi-port discharge valve 3 connected to an inlet/outlet port 4, 4a, 4b of the said waste intermediate tank 1, and a drive motor 5 to actuate said multi-port discharge valve 3.
- the waste system further includes means (not shown) for generating negative or positive pressure inside the said waste intermediate tank 1.
- the multi-port discharge valve 3 is configured to provide, in a first working position, direct communication between the toilet bowl 2 and said waste intermediate tank 1 when negative pressure is supplied inside said waste intermediate tank 1, and configured to provide, in a second working position, direct communication between the waste intermediate tank 1 and the waste storage tank (not shown) when positive pressure is supplied in the said waste intermediate tank 1.
- the multi-port discharge valve 3 comprises a valve body 6, preferably a valve body of synthetic material, and a valve element configured in the shape of a rotating element 7 to be housed inside a cavity of said valve body 6.
- the said rotating valve element 7, preferably a rotating element of steel or aluminium material, is adapted for opening or closing, in said first working position, a passage of fluid between the toilet bowl 2 and the said waste intermediate tank 1, and also adapted for opening or closing, in said second working position, a passage of fluid between the waste intermediate tank 1 and the said aerated waste storage tank (not shown).
- the multi-port discharge valve 3 is a single 3-way discharge valve, or a valve of three ports, connected to a single inlet/outlet port 4 of the waste intermediate tank 1.
- the multi-port valve is a discharge valve with four ports, connected to a first inlet port 4a of the waste intermediate tank 1 and to a separated outlet port 4b of the same waste intermediate tank 1. This embodiment has the advantage of avoiding an accidental waste back-flush, and confers more safety to the system.
- the said rotating valve element 7 is configured in the shape of a tubular element provided with a pair of through holes 7a and an interior separation plate 7b adapted to avoid direct communication between the toilet bowl 2 and the waste storage tank (not shown) in any working position of the discharge valve 3.
- FIGs 5a and 5b depict two working positions of the rotating valve element 7 of the discharge valve 3 where it can be seen, in figure 5a , the interior separation plate 7b defining inside the said tubular element a first conduit for waste passage 8 that connects a first port 9 of the valve body 6 to a second port 10 of the valve body 6.
- the same interior separation plate 7b defines inside the said tubular element a second conduit for waste passage 11 that connects the second port 10 of the valve body 6 to a third port 12 of the valve body 6.
- Figure 5c shows a close off rest position of the discharge valve 3 wherein the rotating valve element 7 close off the connections with the waste intermediate tank 1 and the waste storage tank (not shown).
- the rotating valve element 7 comprises an end section 7c provided with a gear (not shown) configured to be meshed with a worm-gear shaft 13 of the drive motor 5.
- the shaft 13 of the drive motor 5 is arranged to directly engage the gear provided in the rotating valve element 7.
- the drive motor 5 has been provided with a housing 14 for receiving the geared end section 7c (geared not shown) of the rotating valve element 7.
- FIGS. 1 and 2 show flanges 15, 16 and 17 of the valve body 6 for connection to the toilet bowl 2, to the waste intermediate tank 1 and to the housing 14 of the drive motor 5.
- Each of said flanges is provided with a water-thigh seal receivable in a recess formed on the valve body 6 itself.
- a waste cutting element 18 has been arranged between the adjacent surfaces of the second port 10 of the valve body 10 and the rotating valve element 7 as shown in figure 5a .
- the said cutting element 18 is arranged so that eventual solid parts upon valve closure are conveniently cut thus no preventing the valve from closing.
- the different elements of the system are activated from a control panel (not shown) either directly or by means of pneumatic electrovalves fed by a compressed air source (not shown) through pressure regulators (not shown).
- the control panel receives signals from a manual switch arranged next to each toilet bowl 2, which activates the operation cycle.
- the user of the WC cabin will push the manual switch next to the toilet bowl 2, which will activate the drive motor 5 for actuating the rotation of the rotating valve element 7 of the multi-port discharge valve 2 from a rest position to the first working position (see, figure 5a ).
- a positioning sensor reading (not shown) of the rotating valve element 7, which is associated to a processing and control unit of the system, will activate an ejector (not shown) to generate negative pressure (partial vacuum) inside the waste intermediate tank 1 so as to cause the waste to be transferred to the said waste intermediate tank 1.
- the processing and control unit will activate the drive motor 5 for actuating the rotation of the rotating valve element 7 from the first working position to the second working position (see, figure 5b ).
- a position sensor reading (not shown) of the rotating valve element 7 will activate the ejector to generate positive pressure inside the waste intermediate tank 1 so as to cause the waste to be transferred to the waste storage tank (not shown).
- the rotating valve element 7 close off the communication of the toilet bowl 2 to the waste intermediate tank 1 and the aerated waste storage tank (not shown).
- the above-mentioned ejector (not shown) is known in the state of the art. Its operation is based on forcing air to pass through a nozzle and using the negative pressure created therein to extract air from the waste intermediate tank 1 by the Venturi effect and thus creating a partial vacuum. The air supplied and the air extracted from the waste intermediate tank 1 is expelled to the atmosphere.
- the present invention allows obtaining a waste transfer system that stands out from those currently available in the market in terms of efficiency and reliability because a single discharge valve 3 regulates the flow of the waste to the aerated waste storage tank. Moreover, the system has a lower cost than those offered in the market because it has less components and less operations of maintenance.
